Area Forecast Discussion National Weather Service San Francisco Bay Area 1042 AM PDT Fri Apr 10 2020

SYNOPSIS. Band of showers stretching from Santa Clara county southwest towards Monterey county will dissipate shortly after sunrise this morning. Otherwise look for mostly cloudy and continued near or slightly below normal temperatures in the 60s today. A gradual warming trend through the weekend and into early next week with no rain in the forecast at this time. Inland areas will warm into the 70s to around 80 degrees. Long range models indicate light rain chances may return around the weekend of April 18-19th.

DISCUSSION. as of 9:22 AM PDT Friday . Water vapor imagery shows the stubborn upper level low spinning over southern California this morning. Closer to home, a mixture of clouds and sun have been observed with plenty of low- and mid-level remnant moisture. Radar has been switched back to clear-air mode as precipitation chances have diminished across the Bay Area. Afternoon high temperatures will warm by a few/several degrees for most communities this afternoon with widespread 60s expected. Can't rule out a few isolated low 70 reading in the North Bay and in the Salinas Valley. This warming trend will continue into the weekend and into early next week. For additional forecast details, please refer to the previous discussion section.

PREV DISCUSSION. as of 2:45 AM PDT Friday . Band of light showers is stretched across the region from Santa Clara county down along the Big Sur coastline. Light rain started falling just before midnight for places like Watsonville and Monterey with a few hundredths being reported. This jet streak is rotating around the upper low over Southern California and forcing for ascent is modeled to end quickly with most showers ending between 12-14z. Elsewhere skies are mostly cloudy with abundant low level moisture and clouds in place keeping overnight lows mild with 2 am temperatures in the 50s.

The upper low wont bring us any more precip today but model cross sections show plenty of clouds through the day with the most sunshine forecast over the North Bay. The airmass will be modifying as the core of the low slowly exits our region allowing for seasonably mild afternoon highs into the mid and upper 60s.

As the low finally ejects a ridge of high pressure over the Eastern Pacific will nudge towards the coast. A deep trough over the eastern half of the country will keep the ridge axis offshore keeping any serious warming in check. Nonetheless after a relatively cool last few weeks we should see noted warming with highs back into the 70s and even some lower 80s into next week. Onshore flow near the coast will keep lower 60s in place at the beaches with cold sea surface temps around 52-53.

The MJO is forecast to strengthen and move into phase 2 about one week from now with some of the PNA ensembles showing a negative phase heading into next weekend. The operational gfs and ecmwf bring a weak trough onshore for the weekend of April 18-19th while the blend of models has PoPs around 5%.

AVIATION. as of 10:45 AM PDT Friday . for 18Z TAFs. Lingering low level moisture manifesting as widespread stratocumulus across the region late this morning. This has resulted with widespread BKN-OVC decks AOA 2000-3500 ft as many of the terminals and is expected to persist into the afternoon. Brief lifting and reduction in cloud cover possible for inland sites into the mid to late afternoon but a marine stratus deck is forecast to push inland overnight tonight into tomorrow morning. The marine deck is expected to be thick and robust with bases as low as 1500-2000 ft into Saturday morning. Winds generally light to locally breezy onshore, peak winds to around 15kt near the coast this afternoon.

Vicinity of KSFO . Generally MVFR with BKN-OVC bases 2000-3500 feet today, with possible reduction down to FEW-SCT decks into the afternoon. Low clouds associated with marine stratus deck return overnight, with bases down to 1500-2000 feet into sunrise Saturday. Peak onshore winds during the afternoon around 14kt today and tomorrow. Marine layer returns tomorrow night as well.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . MVFR. BKN-OVC decks through majority of day around 2500-3500 feet. Light to briefly breezy onshore winds near the coast today. Marine stratus will come in later today with bases down to 1500-2000 feet into sunrise Saturday morning.

MARINE. as of 10:36 AM PDT Friday . Northwest winds strengthen to become locally moderate today and through the weekend. The strongest winds today will be in the outer waters north of Point Reyes as well as along the typical coastal jets near Big Sur, near Davenport off the Santa Cruz coast, and north of Point Reyes along the Sonoma coast. Northwest winds pick up across the outer waters Saturday and expand to the coast on Sunday. A long period southerly swell will mix with a moderate northwest swell through Friday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
